Ah, the info pages are clear:

     When comparing directories, ignore files and subdirectories whose
     basenames match PATTERN.  *Note Comparing Directories::.

It would be nice if the manual page would be a little more wordy:

       -x PAT  --exclude=PAT
              Exclude files that match PAT.

This is a little too spartan.

For a submitting a patch, I had trouble accessing the git repo:

    git clone git://git.savannah.gnu.org/diffutils.git

For some reason, the clone turned out to be empty. Is this the
correct location of latest sources?
